HiRISE CAMERA VIEWS THE MARS ROVER 'SPIRIT' AT 'HOME PLATE'

- November 26, 2007

The High Resolution Imaging Science Experiment, or HiRISE, camera onboard
NASA's Mars Reconnaissance Orbiter has taken a new color image of the
feature dubbed "Home Plate" in Gusev Crater on Mars.

The Mars Exploration Rover "Spirit" shows up inside the perimeter of Home
Plate, where it was when HiRISE took the image on Sept. 27, 2007, at 2:19
p.m. local Mars time, HiRISE team member Ken Herkenhoff of the U.S.
Geological Survey, Flagstaff, said.

Spirit is driving toward the safe, north-facing slopes on the north side of
Home Plate, which is toward the top of the image. There it will be
positioned to tilt its solar panels toward the sun for the long Martian
winter. Home Plate is a flat, raised feature that is probably a remnant of a
deposit emplaced by an ancient eruption, Herkenhoff added.

The new color image of Home Plate was created using the camera's blue-green
and red channels, Herkenhoff said. At the time, the camera was flying about
270 kilometers, or about 168 miles, over the surface. At that distance, the
camera could resolve objects about 81 centimeters, or about 32 inches,
across. The sun was about 56 degrees above the horizon in the winter
afternoon sky.

The HiRISE image of Home Plate and others are on the HiRISE Website,
http://hirise.lpl.arizona.edu. HiRISE operations are based at The University
of Arizona in Tucson. Professor Alfred S. McEwen of the Lunar and Planetary
Laboratory is principal investigator for the experiment.

The HiRISE camera is the most powerful camera ever to orbit another planet.
It has taken thousands of black-and-white images, and hundreds of color
images, since it began science operations in 2006.

A single HiRISE image will often be a multigigabyte image that measures
20,000 pixels by 50,000 pixels, which includes a 4,000-by-50,000 pixel
region in three colors. It can take a computer up to three hours to process
such an image.

Information about the Mars Reconnaissance Orbiter is online at
http://www.nasa.gov/mro. The mission is managed by NASA's Jet Propulsion
Laboratory, a division of the California Institute of Technology, for the
NASA Science Mission Directorate, Washington, D.C. Lockheed Martin Space
Systems, of Denver, is the prime contractor and built the spacecraft. HiRISE
is operated by the UA.

this part of new HiRISE image of Gusev Crater on Mars. This detail is part
of a much larger image that the HiRISE camera took on Sept. 27, 2007. The
rover has since been driving north, toward the top of the image. (Photo:
